Description

  The present invention relates to a message transmission device.

  Conventionally, (A) a telephone system is known in which a voice message of a user who cannot answer a call is stored in a server in advance, and the server reproduces the voice message to the other party when calling the user ( For example, see Patent Document 1).

  Also, (B) the user stores a voice memo regarding the telephone conversation with the other party in the telephone terminal, and the telephone terminal plays the voice memo so that the user can remember the contents of the conversation when the other party calls again Such a telephone terminal is known (for example, see Patent Document 2).

JP 2005-217570 A Japanese Patent Laid-Open No. 4-18840

  However, since the technique (A) does not store and reproduce a voice message for each partner, for example, when the partner cannot answer the phone call, the stored message is returned when the partner calls back. I couldn't play it and let the other party know.

  In the technique (B), since the voice memo can be heard only by the user, the other party cannot hear the voice even if the call is a return call.

  In other words, the prior art has the following disadvantages.

  A call between a certain phone terminal (referred to as the caller) and the other party's phone terminal (referred to as the callee) failed due to no response from the callee, and subsequently failed even if there was a return from the callee. The contents of the conversation that would have been sent from the sender cannot be known at the sender.

  For example, it is convenient to store the contents of the conversation as a message and listen to the message at the destination when returning.

  The present invention has been made in view of the above, and an object of the present invention is to provide a message transmitting apparatus capable of transmitting a message stored in a call originator when a call is not established to a call destination.

  In order to solve the above-described problem, a message transmission apparatus according to the present invention includes a first telephone number that is a caller's telephone number in a call failure call that is a call corresponding to a call that has not been established, and a call that has not been established. Message data storage means for storing message data including a second telephone number that is a destination telephone number and a message from the source; a first telephone number equal to the destination telephone number in a new call; Message data retrieval means for retrieving message data including a second telephone number equal to the telephone number of the caller in the call from the message data storage means, and reading the message from the message data retrieved by the message data retrieval means, Message transmitting means for transmitting the message to a call originator.

  For example, the message transmitting device includes means for notifying a caller telephone number in the call that has not been established so that a call from the callee to the caller in the call that has not been made occurs.

  For example, the message transmitting device determines whether or not a telephone number storage unit that stores a predetermined telephone number and a telephone number of a caller in a new call are in the telephone number storage unit, and the telephone number Is stored in the telephone number storage means, it is determined whether or not the call is a call not established call. If the call is a call unsuccessful call, the first telephone number of the caller in the call unsuccessful call is determined. And means for generating message data including a telephone number, a second telephone number as a destination telephone number in the call that has not been established, and a message from the caller, and storing the message data in the message data storage means.

  For example, the message transmission device calls the caller if the caller is disconnected while calling the callee in a new call, or if the callee does not answer the call Means for searching for message data if the caller responds to the call.

  For example, the message transmission device includes means for determining whether or not the call destination can be called in a new call, and the message data search means can store message data if it is determined that the call to the call destination is impossible. Search for.

  For example, the message transmission device includes means for calling the destination or canceling the call so as to correspond to the presence or absence of a control signal transmitted from the source in the new call after the message is transmitted.

  According to the present invention, it is possible to transmit the message of the caller stored when the call is not established to the callee when returning.

(Operation in this embodiment)
FIG. 5 is a sequence diagram showing an example of exchanges between the SIP server 1, the message server 2, and the telephone terminal. FIG. 5 shows an example of telephone terminals A and B for telephone terminals.

  FIG. 6 is a flowchart showing an example of the order of processing in the SIP server 1.

  For example, when the user β operates the telephone terminal B to make a so-called call to the user α, a signal (hereinafter referred to as a call) from the telephone terminal B to the SIP server 1 is generated (FIG. 5: S1). The call includes the telephone number of the telephone terminal B that is the call originator and the telephone number of the telephone terminal A that is the call destination.

  In FIG. 6, when the SIP processing unit 11 receives a call from any of the telephone terminals as described above, the SIP processing unit 11 extracts the caller's telephone number from the call and determines whether the telephone number is in the telephone number storage unit 12 or not. Is determined (S101).

  If the telephone number is not in the telephone number storage unit 12 (S101: NO), the SIP processing unit 11 obtains the destination telephone number from the call and determines whether the telephone number is in the telephone number storage unit 12 (S103).

  If the telephone number is not in the telephone number storage unit 12 (S103: NO), the SIP processing unit 11 performs call processing (S105) and ends the processing. By this call processing, for example, a call is established between the telephone terminals A and B.

  On the other hand, if the telephone number is in the telephone number storage unit 12 (S101: YES), the SIP processing unit 11 extracts the destination telephone number from the call, and sets the first telephone number equal to the destination telephone number and step S101. It is determined whether or not there is a message key in the message key storage unit 13 that includes the second telephone number that is equal to the telephone number of the caller extracted in (S107).

  If the message key is not in the message key storage unit 13 (S107: NO), the SIP processing unit 11 tries to call the telephone terminal (the telephone terminal A in FIG. 5) corresponding to the telephone number of the call destination. The SIP processing unit 11 cannot respond to the call because the telephone terminal A is in use (busy) or there is no user α, or the telephone terminal B is out of the reception range of the wireless calling signal or is activated. It is determined whether or not the call is not established between the telephone terminals A and B such that the call signal cannot be received (S109).

  If the SIP processing unit 11 is in a situation where a telephone call is established between telephone terminals (S109: NO), the SIP processing unit 11 performs a call process (S105) and ends the process. By this call processing, for example, a call is established between the telephone terminals A and B.

On the other hand, the SIP processing unit 11 transmits a signal to the message server 2 and the telephone terminal B through the message server cooperation unit 14 if the call is not established between the telephone terminals (S109: YES) (FIG. 5: S3). , S5), the telephone terminal B is connected to the message server 2 (FIG. 6: S111).
The connection with the message server 2 is for storing a message in the message server 2. At this time, the SIP processing unit 11 uses the first telephone number that is the caller telephone number and the callee telephone number. A message key including a second telephone number is generated, and the message key is transmitted to the message server 2 through the message server cooperation unit 14.

  The SIP processing unit 11 also stores this message key in the message key storage unit 13 (S113).

  Next, the SIP processing unit 11 notifies the caller telephone terminal A of the caller's telephone number (FIG. 5: S7, FIG. 6: S115), and ends the process.

  This notification requests a so-called return call to the telephone terminal having the telephone number. As a notification method, for example, by a character display that can be seen even when the telephone terminal A is busy, if the telephone terminal A enters or is activated within a reception area and performs a predetermined operation, For example, a so-called e-mail can be considered.

  When the SIP server cooperation unit 21 of the message server 2 is connected to the telephone terminal B (FIG. 6: S111), the message transmission / reception unit 24 instructs the telephone terminal B to, for example, , Send out a guidance to send a message. On the other hand, if the user β speaks to the telephone terminal B and an audio signal (message) indicating the content is transmitted (FIG. 5: S9), the message transmission / reception unit 24 converts the audio signal into an audio file, This is provided to the message data generation unit 22.

  The message data generation unit 22 receives the message key transmitted from the SIP server 1 through the SIP server cooperation unit 21, generates message data including the message key and the voice file, and stores the message data in the message data storage unit 23 (see FIG. 5: S11).

  When the user α knows that there is a call from the user β by looking at the notification in step S7 in FIG. 5 and operates the phone terminal A to make a so-called return call to the user β, the phone terminal A A call (turnback call) is transmitted to the SIP server 1 (FIG. 5: S21). The call includes the telephone number of the telephone terminal A that is the call originator and the telephone number of the telephone terminal B that is the call destination.

  In FIG. 6, the SIP processing unit 11 determines whether or not the telephone number of the caller is in the telephone number storage unit 12 as described above (S101).

  As described above, if the telephone number is not in the telephone number storage unit 12 (S101: NO), the SIP processing unit 11 determines whether the destination telephone number is in the telephone number storage unit 12 (S103). .

  If the telephone number is in the telephone number storage unit 12 (S103: YES), the SIP processing unit 11 retrieves the first telephone number equal to the destination telephone number retrieved in step S103 and the retrieval in step S101, as in step S107. Then, it is determined whether or not the message key storage unit 13 has a message key including the second telephone number equal to the telephone number of the caller (S121).

  If the message key is not in the message key storage unit 13 (S121: NO), the SIP processing unit 11 performs call processing (S105) and ends the processing. By this call processing, for example, a call is established between the telephone terminals A and B.

  On the other hand, if the message key is in the message key storage unit 13 (S121: YES) or if it is determined in step S107 that the message key is in the message key storage unit 13, the SIP processing unit 11 means Regardless of whether the telephone number is in the telephone number storage unit 12, a message key including a first telephone number equal to the destination telephone number and a second telephone number equal to the source telephone number is the message key storage unit If it is 13, it is determined whether the destination is busy, out of reception range or not activated (S123).

  The SIP processing unit 11 attempts to call the destination telephone terminal A if the destination is busy, neither out of reception range or not activated (step S123: NO). This call is made continuously for a certain period of time, and at that time, the SIP processing unit 11 determines whether or not the call is disconnected, for example, whether or not the call is answered and whether the caller terminal A is on-hooked. It is determined whether or not (S125).

  If the destination telephone terminal A is able to answer the call for a certain period (S125: YES), the SIP processing unit 11 performs the call process (S105) and ends the process. By this call processing, for example, a call is established between the telephone terminals A and B.

  If the call is disconnected within a certain period or if the certain period has elapsed without a response (S125: NO), the SIP processing unit 11 attempts to call the caller telephone terminal A (S127). It is determined whether the telephone terminal A has responded (S129).

  If the telephone terminal A does not respond (S129: NO), the SIP processing unit 11 ends the process.

  On the other hand, if the telephone terminal A responds (S129: YES), or if it is determined in step S123 that the call destination is busy, out of the reception area, or not activated, the SIP processing unit 11 A signal is transmitted to the message server 2 and the telephone terminal A through the message server cooperation unit 14 (FIG. 5: S23, S25), the telephone terminal A is connected to the message server 2 (FIG. 6: S131), and the process is terminated.

  The connection with the message server 2 is for transmitting a message from the message server 2. At this time, the SIP processing unit 11 is equal to the first telephone number equal to the telephone number of the call destination and the telephone number of the caller. A message key including the second telephone number is searched from the message key storage unit 13, and the message key is transmitted to the message server 2 through the message server cooperation unit 14.

  If the SIP server cooperation unit 21 of the message server 2 is connected to the telephone terminal A (FIG. 6: S131), it instructs the message transmission / reception unit 24, whereby the message transmission / reception unit 24 is transmitted from the SIP server 1. Message data including the message key is retrieved from the message data storage unit 23 (FIG. 5: S27). The message transmitting / receiving unit 24 converts the voice file in the message data into a voice signal, transmits it to the telephone terminal A (FIG. 5: S29), and deletes the message data from the message data storage unit 23.

  The telephone terminal A converts the transmitted voice signal into voice. As a result, the user α can hear the voice, that is, the message of the user β.

Therefore, according to the present embodiment, the message transmitting apparatus, that is, the SIP server 1 and the message server 2, have the first telephone number that is the telephone number of the caller in the call not established call that is a call corresponding to the call that has not been established. Message data storage means for storing message data, that is, a message key and a voice file, including the second telephone number that is the telephone number of the call destination in the call that has not been established and the message from the caller, and the message key storage section 13 and the message A data storage unit 23;
Message data retrieval means for retrieving message data from the message data storage means, that is, SIP, including a first telephone number equal to the telephone number of the callee in the new call and a second telephone number equal to the telephone number of the caller in the call A processing unit in step S107 or step S121 in the processing unit 11 and a processing unit in step S27 in the message transmission / reception unit 24;
A message transmitting means for reading a message from the message data retrieved by the message data retrieving means and transmitting the message to the call originator, that is, a processing means in step S29 in the message transmitting / receiving unit 24. The message of the sender stored in the message can be transmitted to the destination when returning.

  Further, the message transmitting apparatus notifies the telephone number of the caller in the call not established call so that the call from the callee to the caller in the call unsuccessful call is generated, that is, the processing means of step S7 in the SIP processing unit 11 Therefore, it is possible to return from the call destination to the caller by using the telephone number of the caller.

In addition, the message transmission device includes a telephone number storage unit that stores a predetermined telephone number, that is, a telephone number storage unit 12;
It is determined whether or not the telephone number of the caller in the new call is in the telephone number storage means (S101). If the telephone number is in the telephone number storage means (S101: YES), the call is not established. It is determined whether or not the call has been made (S109), and if the call has become a call that has not been established (S109: YES), the first telephone number that is the caller's telephone number in the call that has not been established and the call that has not been established The message data including the second telephone number which is the destination telephone number and the message from the sender is generated (S113) and stored in the message data storage means, that is, steps S101 and S109 in the SIP processing unit 11. And the processing means of S113 and the processing means of step S11 in the message data generation unit 22, so that the user α, The part of the user receiving the message, the contract of the service can be unquestioned.

  In addition, if the message transmission device is disconnected from the call originator while calling the destination in a new call, or if the destination does not respond to the call (S125: NO), the message transmission device A means for calling a caller (S127), that is, a processing means of step S127 in the SIP processing unit 11, is provided, and the message data search means searches for message data when the caller responds to the call, that is, telephone terminal A In response to the response (S129: YES), when connecting to the message server 2 (S131), the SIP processing unit 11 searches for the corresponding message key, and the message transmission / reception unit 24 searches for the corresponding message data. The callee does not answer or the caller stops the call, and the caller receives a call from the message sending device. If in response to the teeth, it is possible to send a message.

  Further, the message transmitting device includes means for determining whether or not the call destination of a new call can be called, that is, the processing means of step S123 in the SIP processing unit 11, and the message data search means is configured to call the call destination. Is determined to be impossible (S123: NO), the message data is searched, that is, when connecting to the message server 2 (S131), the SIP processing unit 11 searches for the corresponding message key, and the message transmitting / receiving unit 24 searches for the corresponding message data, so that the call of the call destination is omitted, and the message can be transmitted quickly.

  In the present embodiment, if the call destination telephone terminal A is called but cannot be answered (S125: NO), the call is stopped, the caller telephone terminal is called (S127), and this call is called. If the terminal responds (S129: YES), the telephone terminal is connected to the message server 2 (S131), and the message can be heard by this, but it may be as follows.

  FIG. 7 is a flowchart showing another example of the order of processing in the SIP server 1.

  The SIP processing unit 11 connects the telephone terminal A to the message server 2 (S141) if the call destination is busy, not within the reception range, or not activated (step S123: NO). Thereby, as described above, the corresponding message data is searched, the audio file in the message data is converted into an audio signal, the audio signal is transmitted, and the audio signal is converted into audio. Thereby, a message can be heard. Message data is deleted.

  Next, the SIP processing unit 11 determines whether or not a control signal indicating that a connection with the destination telephone terminal B is desired is transmitted from the source telephone terminal A (S143). For example, when the user α who has heard the message operates the telephone terminal A to talk to the user β, the control signal is transmitted.

  If the control signal is transmitted (S143: YES), the SIP processing unit 11 performs call processing (S105) and ends the processing. By this call processing, for example, a call is established between the telephone terminals A and B.

  On the other hand, if the control signal is not transmitted (S143: NO), the SIP processing unit 11 disconnects the call (S145) and ends the process.

  In addition, since it is the same as that of this Embodiment other than the process demonstrated here, the description is abbreviate | omitted.

  Therefore, in the process of FIG. 6, if the destination telephone terminal A responds to the call (S125: YES), the message cannot be heard, but as described above, the message is transmitted in advance (S141), Such inconvenience can be prevented.

  In addition, after the message is sent, the destination α is called or canceled so as to correspond to the presence / absence of a control signal transmitted from the caller in a new call. It is possible to select whether or not to have a conversation with the user β. For example, if the message content is sufficient, it is possible to avoid wasting time without talking. Or, if the message content is insufficient, this can be supplemented by conversation.

  In other words, the message transmission apparatus is a means for calling the destination or canceling the call, that is, in the SIP processing unit 11 so as to correspond to the presence or absence of a control signal transmitted from the source in a new call after the message is transmitted. Since step S143 is provided, it is possible to select the merit by the user α as described above.
